That would surprise me, since Java performance relies on a JIT compiler. Very different framework. There are specific optimizations employed by the JVM that could be adopted by other backends - for example its JIT has specific interior knowledge of z196 and z114 processors, for which it generates machine dependent out-of-order instruction sequences. -- David Andrews A.
